Osmosis: Osmosis is the movement of a solvent across a semi-permeable membrane. It is a passive process which is used by living organisms to maintain water balance. Answer and Explanation:1 Chemiosmosis produces ATP. It is the process by which ions or charged particles move across a semi perm...
The ATP made during glycolysis is generated by what? What does the Krebs cycle use to generate ATP? Where does macromolecule digestion occur? How does phosphorylation affect cell signaling? During which step of cellular respiration is the most ATP produced?
Why would an organism use fermentation to generate ATP? Why is ATP an effective energy carrier? Why is cellular respiration considered to be much more efficient than glycolysis alone? Why don't neurons use lipids for energy? Why is ATP well-suited as a metabolic energy currency?
The ATP production of fermenting cells does not depend on a membrane potential and they are still able to generate enough ATP through glycolysis to power their proton pumps in the presence of DNP. For mammalian cells, it was shown that addition of H2O2 depletes the ATP levels by inhibiting ...
When exercise intensity reaches a moderate level, cells use glucose to produce ATP. As the intensity of the activity means greater flow rates, the pyruvate and hydrogen ions produced by glycolysis will undergo lactic fermentation, resulting in the production of lactate ions (4). A...
In fermentation, the enzymes involved can be reused in the extracellular medium. 6. Similarity Between Fermentation and Anaerobic Respiration: - Both processes ultimately produce ATP, meaning they both generate energy from their respective reactions....
ATP needs to be “produced” by the body through a series of biochemical reactions called theKrebs CycleorCitric Acid Cycle. This cycle starts with a molecule calledAcetyl-CoA: during these reactions, the energy stored within Acetyl-CoA is “liberated” to generate ATP. However, how Acetyl-...
The pancreatic β-cell's "metabolic wiring" is uniquely geared to generate secondary signals. Glucose enters the β-cell by the GLUT2 transporter, where it is phosphorylated by glucokinase and channeled to glycolysis. The combination of GLUT2 and glucokinase (with their Km values in the mmol/L...
Which process of aerobic respiration produces the majority of ATP? a. Pyruvate oxidation b. Glycolysis c. Oxidative phosphorylation d. Citric acid cycle What process of cellular respiration is dependent on receiving hydrogen pairs from glycolysis and citric acid cycle in order...
During cellular respiration (catabolizing glucose), no ATP molecules are generated: a. during the Krebs cycle. b. via the movement of H+ through ATP synthase in the mitochondria. c. during the linking phase. d. during glycolysis. In Krebs Cycle: a. ...
